react-native android 环境报错 node , Could not start 'node',error=2, No such file or director
1. android 环境下报错
Could not start 'node' 或者 error=2, No such file or directory
A problem occurred starting process 'command 'node''
错误信息 :
我的项目构建失败,因为它使用了不正确的目录来运行 Node.js。如何为这些编译时任务设置节点目录? 具体任务是: 应用程序:recordFilesBeforeBundleCommandDebug 以及相关的错误: org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':app:recordFilesBeforeBundleCommandDebug'. Caused by: org.gradle.process.internal.ExecException: A problem occurred starting process 'command 'node'' Caused by: net.rubygrapefruit.platform.NativeException: Could not start 'node' Caused by: java.io.IOException: Cannot run program "node" (in directory "/Users/me/Code/appname/android/app"): error=2, No such file or directory Caused by: java.io.IOException: error=2, No such file or directory
解决办法:
在 项目/android/app/build.gradle 文件添加下面代码
第一种:添加-> nodeExecutableAndArgs: ["/usr/local/bin/node"]
project.ext.react = [ entryFile: "index.js", nodeExecutableAndArgs: ["/usr/local/bin/node"] ] 第二种: 添加下面代码ext {
react = [
nodeExecutableAndArgs: ["/usr/local/bin/node"]
]
}
注意: 上面 /usr/local/bin/node 是自己本地启动【安装】node的路径,mac系统可以在终端输入 which node 命令 来得到node的路径
在rn 新的版本中上面方法无效,可以试一下下面的方法
1.打开终端,运行这个 open -a /Applications/Android\ Studio.app
2.然后同步Gradle
